4.2 Diversity and habitat sharing between pollinators
Among all pollinators, 61 species (Figure 3) were common in all the
studied habitats which show the heterogeneous habitat choice of wild
bees and wider temporal range of activities of flies (Willcox et al.,
2019). Hoverflies feed on varieties of food resources in different
stages of life. For instance, the larva of some hoverfly develops in a
close canopy while adults of the same fly hover in open flower–rich
biotopes (Gittings et al., 2006). Furthermore, the abundance of
hoverflies increases with proximity to the forest (Laura Moquet et al.,
2018). Likewise, many bee groups require different habitats for nesting
and foraging (Franzén et al., 2009) and also different spatial foraging
distances made by bees like Bombus spp. and Xylocopa spp.
(Greenleaf et al., 2007). This could be a probable reason for the
presence of some bees group in all habitats. Butterflies too show a
different kind of preference of habitats in their life cycles (Janz,
2005). Females dwell in grassland for oviposition while foraging in
flower–rich habitats (Evan et al., 2020). In contrast, some pollinators
are confined to only one kind of habitat. For an instant,Vollucella trifasciata and Bachha maculata were recorded
from forest habitats only. This result can be linked with the findings
of Coe, 1964.
